India’s Hydrocarbon Outlook 2024 34 A Report on Exploration & Production Activities The category of basins is subject to upgrade upon change in resource maturity at basin scale. Category III basin may be upgraded to Category II in case, there is a discovery or Category II to I, if discoveries are commercially produced. Since category is linked to resource maturity, basin grouping will be meant There are 9 offshore basins having an area of 1.73 million sq km, out of which 0.41 million sq km is located in shallow water up to bathymetry differently to conventional and unconventional resources. For example, Satpura-South RewaDamodar basin is a Cat III basin for conventional resources, which are yet-to-be discovered, but it will be deemed Cat I basin for unconventional (Coal Bed Methane) as it is commercially producing CBM gas.
